ANGUS DANIEL MOCALL, OF LAURINBURG, NORTH CAROLINA.

SASH- FASTENER.

SPECIFICATION forming part of Letters Application filed August 31, 1885.

To all whom it may concern.-

Be it known that L'ANGUS D. MOGALL, a citizen of the United States,residing at Lau: rinburg, in the county of Richmond and State of NorthCarolina, have invented new and useful Improvements in Sash-Holders, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention has relation to improvements in a combined sash-holder andlock; and the novelty consists in the peculiar construction andcombination of parts, substantially as hereinafter fully set forth, andparticularly pointed out in the claim.

The object of my invention is to provide a device of the classdescribed, which shall be capable of use upon either the sash or window-;frame, which shall be capable of being reversed to serve as a lock toprevent the sash being opened, and as a holding device to hold the sashat any desired point of its elevation, which shall combine simplicity,strength, and durability of construction with efficiency of operation,cheapness, and facility of manufacture, ease of application to andremoval from either the sash or window-frame, and which shall dispensewith the use of cords and ropes in a sashbalance, as at presentuniversally employed.

I have shown an embodiment of my invention in the drawings, referring towhich Figure 1 represents my invention in position for use as asash-holder upon the sashes of a window. Fig. 2 is a perspective View ofthe device applied as a lock, a'portiou only of the sash and frame beingshown. Fig. 3 is a detail perspective view of the locking device.

Referring to the drawings, in which like letters of reference indicatelike parts in all the figures, A designates a window-frame of ordinaryconstruction, and B designates the two sashes, free to slide in groovesa in said frame, and each having my invention applied thereto or adaptedto operate thereon.

C designates my improved combined lock and holder, which is made in asingle casting, for strength and durability, and is pivoted upon eitherthe window-frame in such juxtaposition thereto that the arms thereofwill enas a lock or holder, or pivoted on the sashframe at or near thesides thereof in such jux- Patent No. 336,932, dated March 2, 1886.

Serial No. 175,788. (No model.)

taposition to the window-frame as to engage one of the series of stopsformed or arranged thereon, so that said device shall be used either asa lock or holder, all of which will more fully hereinafter appear.

' Each sash is provided with one of the improved locks, which ispivoted, as at c, the pivot-pin passing through a flattened plate, d,having a serrated edge at one side thereof.

I) designates a flange extending around the remaining edges of the plate(Z and adapted to counterbalance the weight of the arms E F, to enablethe device to be turned easily and freely on its pivot c. The arm orshoulder E extends laterally from the plate and is provided with a taperto the point thereof, as at c. When the arm E is throwndown in itsinclined position, as shown in Fig. 1, it engages one of a series ofstops, G, and serves as a lock to prevent the sash from being elevatedfrom the outside or until such lug or arm has been forced fromengagen'ient with the stops with which it locks. The arm F extendslaterally at right angles, or nearly so, to the arm E, and is preferablycurved and tapered, as shown, said arm extending from the rear or undersurface of the locking-arm E.

\Vhen the device is in the position shown, Fig. 1, so that the arm F isin engagement withone of the series of stops G and bears against eitherthe frame or the sash, it serves as a holder to secure the sash at anypoint of its elevation, the lug or arm engaging with the under surfacesor edges of the stops in the latter instance.

The casting C may be pivoted to the sash at one side thereof and engagewith the stops G on the wiudow-frame, as shown in the upper half of Fig.1; or it may be pivoted on the window-frame, so that it will engagethestops on the window-sash. Either of these arrangements of parts may beemployed without departing from the principle of my invention; but inpractice I prefer to combine both arrangements in one window, as shownin Fig.

1 of the drawings; but I would have it under- IOO It will be observedthat the device is free to turn on its pivot, or be reversed, to bringeither of the arms in engagement with the stops, according to the use towhich it is designed to put them, and that the heavy tapered flangethereof counterbalances the weight of the arms and makes the device easyof operation.

The device secures great simplicity, sti en gth, and durability,being'cast in one piece and not liable to breakage, is very cheap andeasy of manufacture, thus bringing it within the reach of all, can bequickly, easily, and readily applied to and removed from the frame orsash by unskilled persons, and is thoroughly effective and reliable inoperation.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The centrally-pivoted circular plate d, having an enlargement oroutwardly-projecting lateral flange, D, arranged around a portion of therim of plate (I, a pointed arm, E, at the termination of the flanged rimD, projecting beyond the serrated plate cl at an angle thereto, and anarm, F, extending outwardly from the rim D at an angle to the arm E,whereby the arm E is adapted to lock the sash and the arm F to serve asa sash-holder when the device is reversed, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signaturein presence of two witnesses.
